What is the LCM of 3 7 11 and 13?

To find the Least Common Multiple (LCM) of 3, 7, 11, and 13, we need to first prime factorize each number. The prime factors of 3, 7, 11, and 13 are themselves as they are all prime numbers. The LCM is then calculated by multiplying the highest power of each prime factor present in the numbers. Therefore, the LCM of 3, 7, 11, and 13 is 3 x 7 x 11 x 13 = 3003.
